Straightening a valuable drill bit
Years ago, I bought a 16mm parabolic drill bit from a flea market in Frankfurt. Such drill bits are quite valuable. The price of this particular drill bit when new is 200 euros.
At the flea market, the price of the drill bit was 20 euros, which I thought was a good deal.
Unfortunately, I noticed that the drill bit was badly bent and in its current state completely unusable.
Could it be straightened?

I would say go for it. It would be a good "project" to straighten with a hydraulic press. I would only press it slowly so you can follow the process. Method....press-check for straightness-press-check ......you get the idea.
Just do it!
Kind regards Rod
